Be it known that '1, ANDREW 'HUBERT, a

citizen of theUnit'ed Statesof America, re-

siding at Sparta, in the county of Kent and State of Michigan, haveinvented certain new and useful Improvements in Tractors; and I dohereby declare the following to be a full, clear, and exact descriptionof. the invention, such as will enable others skilled in the art towhich it appertains to make and use the same. I f

This invention relate to tractors. It is an. object and purpose of myinvention to provide a tractor-which maybe moved by a. directconnection.ofan e gine carried'by the tractor with. of the wheels thereof and whichalso, while it is beingused at work, maybe moved back and forth across afield by useof a cable attached to suitable anchors at eachend of thefield. A further object of the invention resides in many details ofconstruction whereby these operations. may be-performedtogether with various other novel features 01: operation such a the movingof the tractorlaterally at each I end of the field substantially at right angles tothe path of movement'which it takes in going back andforth across thefield in. the provision of novel means for changin the direction of thewheels at each. end o i'the tractor either separately or together, and

, particularly in a novel constructionfwhich,

driven by the engine, actsupon the cable to move the tractor overtheground to perform the work thereon. All of these features to gether withothers not specifically enumerated will appear as understandin is had ofrality ofv which are used in the cable winding mechanism of thetractor.

nthe construction as shown aplatform 1 is provided at ,jeach'side beingsupportedby transverse axles .2 which at their. ends are Wheels ateitheror both 1 I a Z 607,. Y Like reference characters refer to. like formedwith forks 3between thearins. which are pivotall ounted the knuckles 1,

7 previouslydescribed. Shafts 11 attheir meeting ends, substantiallymidway between i 5 V the sides of the platform 1,: are connected by anysuitable di erential mechanism with n the case 14, this mechanism, asit-fQlmS no part of the invention, not being specifically shown ordescribed. The shafts are driven by the chains 15 passingaroundsprockets 16 loosely mounted on the engine shaft'l'l ,7 which inturn'fis driyenjby an engine 1,8.of j

anysu'itable type, preferably a reversiblein-i ternal combustion engine.

a wheel 16 loosely mounted onj shaft 17,

' this clutch being operable by a lever 20 so as V A clut h i J splinedn the shaft-17 and has a clutch face 19 7 adapted to engage with similarface 01 toengage with and connect the driven shaft with the differentialmechanism shown as drivingthe sprocket wheels whereby when the engine isrunning all ofithe' wheels Wi1l be drivenin' the samedirection.

21 are connected to breast with the knuckles 4 and extend inwardly,

the arms for eachv axle'being connected by a Worm gear keyed thereto.Meshing with cross rod 22. An arm 23 mountedona vertical'shaft 24 isattached at'its' end to each rod 22 between the ends thereof, saidshafts 24 being mounted on the axles and near its lower end but abovethe arm 23 having a each worm gear is a worm 26 fixed to the end of avshaft 27, said shafts extendingetoa ward each other and coming togetherunder-;

neath the'platform l. Extending upwardly from the platform is a verticalsleeve 28 in "which ismounted the shaft 28 ,jits upper end having asteering wheel 29 fastened thereto while at its lower end below thetable it carries a bevel pinion 30. Splined on-each "shaft 27 is a bevelpinion 31, each being conne'ctedwitha bell crank lever 32 pivotallymounted on the sleeve 28 and operable by the vertical rods 33 which,extending alongside the sleeve 28 are connected at their upper ends tooperating handles 34 pivotally connected to a sleeve'35 immediatelybelow the wheel By operation of either one or both handles 34 either oneor both ofrthe pinions 32 maybe niadeto engage with the pinion and inthis'manner either pair of wheels at an end of the platformor bothof thepairs of wheels may be niadeto change direction on turning'the steeringwheel 29. The construction is such that the wheels 6 may be turned atpractically right angles to their position shown in. Fig. 1 and theentire tractor moved laterally a-desired distance equal to the width ofthe ground operated uponjby'any suitable toolsdrawn by the tractor jwhen the end'of the field is reached; and this movement of the tractorsidewise will be accomplished by a direct drive of the wheels throughthe mechanism just described when it is connected to 'the engine.

. The engine shaft 17 is extended for a distance beyond the clutch 19,its end being mounted in any suitable bearing in the bracket36. Looselymounted upon the shaft r 43 as shown in Fig. 6. The central shaft 40 nalbox r 41 at its end carries a similar gear'45ofthe at its end beyond theplate, 39-carries a spur gear 44 for the shaft and each'of the shaftssame size as shown in Fig. 3. There are six of the shafts .41 andaccordingly six gears 45.- Idle p'inions 46, three in number are whichis held stationary on the jourmounted on studs 47 projecting outwardlyfronrthe plate 49, each of these 'idlepinions' V meshing with thecentral gear 44 and with 1 two of the gears 45. This construction .isfully disclosed in Fig. 3. V

formed by g@n-3s, 1ate'a9, and the cross 7 A- cable '48 isf-wound aroundthe reel members 41 and 42, said cable being turned several times aroundthereel and seating in. :the; grooves 43 of the rollers 42.;1At each endof the platform substantially manna 'inent'with the cable as it leavesthe reel is a" roller 49 mounted on abracket 50. Similarly' adjacent oneside of the platformi'at. j

eachend is a roller 51 mounted on a bracket :52 and this bracket beadjusted tosev- "e'ral different positions on the plate 52*,to ifcorrespond with the. width that is worked by the'tractor as itjmovedjacross the field. Between rollers 49 and 51 a bracket 53 isconnected to each axle 2, it carrying a di V videdshaft'54 which at itsouter endis pro-. vided with a crank 55 and at its inner end with a forkor plate'56 on which is mounted two pulleys 57. A strong coil spring 58'is tension in spring 58.

The operation of in fulllines in -Fig.1 l, which is in direct linementwith "theuwin'ding reel is carried across the field and secured to anysuitable anchor as post 48 133: moving the clutch. jso' that'its clutchface l9 positioned oppo j;

45 and' 46, it being apparent that if this-' structure was not presentthefrotation' of the; reel would shift the cable toone end ofthe reeluntil stopped byeither the gear 38 or plate 39. The cable 48 behindthetractoris carried over the two pulleys 5 and the pulley'51 and issecured to an anchor at the .1 posite end ofthefield. The distancegbe-Ttween pulleys 49 and 51 is the width'of the strip of ground thatanytool'drawnbehind s 125 thetractor covers and if divid s r p. ofground is to be worked a bar maybe secured to the support 52 to extendthe pulleybl laterally yond the side ofthe tractor. 1 The cable behindthe tractor has its slack taken up bythe spring 58, it beingapparentjthat attached to the twofp sfof thedivided; shaft and a pawl 59onfthe crank 55 engages Y with a ratchet 6O for holding the crank infposition when it is turned to increase .the f thetractor' may now be j'set forth. The end of the cable 48, shown r sired tension to the-spring'5'8' and that this tension istransmitted to the cable to take upthe slack betweenthe tractor andth'e anchor behind it. Whenthe. end ofthe field-is reached the clutch is shifted andthe tractorinio'vedlaterally (referringto Fig.

1}to the left. 'Thecable is then dis'associ-' ated from thepulleys 51and 57 at'the rear end and is threaded over the pulleys 57 and 51-a-tthe'opposite end as indicated in dotted linesin Fig. 1, theenginesreversed and the tractor then drawn backacross the field, itbeing-evident that in order to change the cable 48 at the lower end inFig. 1 from the full line position to the'dotted line position theanchor must be moved over a corresponding distance, this moving of theanchor occurring whenever the end of a field is reached. In practice Iprefer to set two posts a distance apart and stretch a heavy chainbetween them to different links of which the cable may be attached sothat i at each passage of the tractor across the field a new post neednot be set. 7

Various changes in vdetail of construction may be resorted to withoutdeparting from my. invention which is defined in the appended claims.Accordingly I do not wish to (be limited to the specific structure.disclosed 'but consider myself entitled to all modifications ofstructure falling withinthe scope of the claims.
